My invention relates `to means tor supporting brake hangers pendently troni the'truck frames and involves a construction adapted to the luse of either a continuous link type ot hanger or a lol-shape type of han gerj thus perinitting an interchange othangers. f

The invention involves a keeper element for the hangers or the supporting pin, when the U-shape type of hangerv is employed,

which, as well as the supporting pin,A are so Constructed as lto provide non-circular or ir-A regular Jformed matching'suripaces.or interengaglng portions whereby frotation o'l the pin 1n the keeper element is preventedduring drawing, whereinf Figure l isa side elevation o'l' a portion ot' a truck frame with an lextension or arm formed to receive atype of keeper element 5 and brake hanger; the ligure illustrating a U-shape type of hanger and its supporting pin; portions off the hanger being broken away. Y

Figure 4 is a detaily perspective view otniy improved keeper element als employed in Figure l. f v

Figure 5 is a side elevation ot'the extension or armv of the truck traine ,illustrating the substitution of a continuous type of link hanger, which is partially broken away.

My invention contemplates 1 a keeper element adapted to be inserted in a socket formed in the arm or extension l5 which is preferably7 l'ormed integral Awith the truck frame7 ajpor`= tion et tilie'lat'f id "ted at 16., 'The the oscillator-yor swinging moven'ientsolI the Chosen for illustration in the accoinpanying .groove formed by the lue 1.7, namely by havin Ving accomplished by passing tl vpin Qd'throngh aperture 23i conjiparative lateral width and arranged to irovider an elongatedrectangular pocket Vor socket open toward the wheels olf the truck. The flange or rib atene Aend of the pocket is shown otl'set to provide the extended portion ,naar

-ner side of the truck frame, withthe sidev f `of the arm disposed toward the wheels of the )truck provided with a continuousiange 1'? ofV 18 of the pocketor socket. The pocketlor i socket formed by the continuous flange 17v in the particular' exemplifieation is also shownprovided with transversely disposed ribs 19 at points' intermediate ofthe ends of the lpocket or socket as'seenl in Figure 3.

rllhe pocket or socket is adapted to receive a keeper element 2O.l

The keeper element consists oan elongated plate of thickness commensurate withthe vertical depth of the pocket or socket inthe extension l5 and of. length vsubstantially equal v'to the length ofthe main portion of said pocket or socket. The keeper element is cut awayor slotted transversely adjacent lto the f ends to providehanger linki receiving passages 21, 2l; while' the parallelly disposed ends 22,

22 are apertured at 2 3 toA receive theV hanger supporting'pin 24e whereby the U-shapelink or hanger 25 is pendently supported in place. Thepin 24: is adapted to pass throughthe upper eyeletted ends of the link vhan ger 'as shown after being passed through one end oir vof the supporting pin'24 or' intermediate part oli a continuous link hanger when same to beV substituted `'l'or the U-shape hanger; the 26 being. therefore in alignment with the apertures 23, 2?)v in they end portions 22 of the keeper element. The

vthe element.v The `keeper element,'interline-,y

length of the lip or lug 26 is preferably such. l

that it will lit in between the transversely disposed ribs 19 in the pocket or socket formed in' the arm l5 of the truck frame.

3y reason ol the continuous rib orrlange thev ends of the pocket or socket closed, it isapparentthat longitudinal movement of theshanger supporting vpin 2llfis impossible atter: the elements have been properlyl assembledY vin place; this beA y let the

e supporting ends of the hanger and the other end of the keeper plate.r The assembled eleineiits are then inserted into the pocket or socket-Vv orined on theV vertical face1of, ,`thearin or extension 15,`by passing the keeper element .f1 edgewise'into the pocket, and the keeper elenieiit 2O locked in place in any suitablelnianner, as for example by the `bolt 27 Which is adapted to pass through registering apertures in the upper and lower portions of the Y iaiige'l? as vvellas tl'ii'ough the!aperturel 28 of the keeper element 20. l

Inrpiactice, it'lias been found that the constant: vibrations andk oscillatory "nievements of theA brake hangers `Will causethel hanger supporting pin-24 ,torotate iiifl'i'io tional relationy with the keeper eleiiieiitand as a result subject the latter as ivellpas tlie pinto considerable Wear. VVIn order to 'eliiiii 'i nate 'this condition, I provide thekeepei ele'- infentz20 at onefend with an'extension or lug 29 preferably to'the outer side ofthe keeper element, namely? beyond the shearing point adjacent to the end of the pin; the lug being disposed across a portion of fthe' aperture 23 in said end soas to leave only a segii'ieiitkal portion of the aperture exposed as shown in c Figure l at the right hand end vof the'keeper element. v Y

".T'he supporting pin 124': is provided with a ilat'facedreduced extension or `cut-away por-V tion at one end as shown at-30 in order that the flatface of the extension at the end of the pin niayrest on the flat iacehofv the. lug 29 While the semi-'circular` partof the pin eX tension or endpasses through the semi-oircular aperture in the end of .the keeperelementvand rotation ofthe pin therefore made impossible. It is appareiitthat any suitable non-circularformation at the end of the pin may be employed.' `Theiiiiterengaging portions o't the pin and'l'ug are preferably arranged beyond the bearing points of the pin in the ends oi" the keeperfeleineiitand therefore beyond the shearing points on the pin saine time providing Aa construction which permits interchange of the l'different types of Vhangers y'vithoutjy interfering with: ,the neces- Isary oscillations fof the continuous -link .hanger yyvhe'n employed.

Where 4a substitution oi? the continuous op@ ,oft link phafisershfwe 311111' Figur@ 5 'is desired, the supporting pin` 24 *is remove-d .and the upperrend. of the link'il placed into the groove formed by''ciirved li'p 26 ofthe ,vention keeper eleiiient and thekeeper eleiiientwitli however, may be modified in certain respects wwijthoutjdeparting from the spirit of the in- What I. claim'. is `zel; In a brake hanger support, a keeper ele- Vnient `comprising a transversely slotted .ineinber to provide 'passages 'adi aceiitthe. ends for the sides of a brake haiiger1,the portioiioi';1 the member Yintermediate of said slots being lon-V gitudinally groovedvvhile the ends othe:y
